Title:
ELECTRICAL ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2020/179578
Kind Code:
A1
Abstract:
A differential device 5 has a driving rotational solid 2 capable of rotating about a rotational axis O, a planetary rotational solid 52 capable of turning on its own axis and of revolving about the rotational axis O, and a driven rotational solid 3 capable of rotating about the rotational axis O. The planetary rotational solid 52 is caused to mesh with both the driving rotational solid 2 and the driven rotational solid 3 to form a first reduction gear 5a between the planetary rotational solid 52 and the driving rotational solid, and to form a second reduction gear 5b between the planetary rotational solid 52 and the driven rotational solid 3. The planetary rotational solid 52 is driven by an electric motor 4 and the driving rotational solid 2 is driven by driving force from an engine. An intake camshaft 32 is provided to the driven rotational solid 3, and an exhaust camshaft 22 is provided to the driving rotational solid 2.
